Abort!

It's already a 24-hour recycle in my book.

Clock has been reset to T-15 minutes, but due to warming propellant this is likely to be a scrub.

The 67-minute window opens at 7:07 p.m. ET

Commentator says this was an auto-abort. Will try again tomorrow.

End of webcast.

Falcon 9 auto abort at T-30 seconds. Rocket and payload are in good health—teams are working toward tomorrow’s 69-minute launch window opening at 7:06 p.m. ET

Thanks again Steven.

Abort at T-30 seconds was triggered by flight computer. Higher than expected first stage cryohelium decay. Will investigate that and set up for 24 hour recycle.

What does "cryohelium decay" mean? Haven't heard of that term before.

Audio stream has ended and again has not been made private. Looks like a change of policy at SpaceX.

SCRUB. SpaceX has called off tonight's launch at Cape Canaveral after the Falcon 9 rocket's on-board computer detected a higher than expected decay rate in the first stage helium system.

The next launch opportunity is tomorrow at 7:06pm EDT (2306 GMT).

Decay relates to temperature or ‘leak’?

I believe that means a decay in the pressure somewhere in the cryogenic helium storage and supply system. This could be due to a leak or a problem in the pressure measurement sensor.

Tiny helium leak (just barely triggered abort), but we take no risks with customer satellites. Standing down to investigate.
